The Libre Graphics Meeting (LGM) is an annual international convention for the discussion of free and open source software used with graphics. Held since 2006 it is organised yearly by a different community working around and about free software in a different location around the world.
The Libre Graphics Meeting aims to attract developers, artists and professionals who use and improve free and open source software graphics applications. By collaborating it allows the development of cross-application assets and enhanced interoperability. Many things are discussed at each Libre Graphics Meeting, including usability, standards, announcements, colour management and furthering the use of free software graphics applications in professional environments.
Constant participated actively in the organisation of many editions of the convention and hosted the Brussels one in 2010.
